Looking for a Marlon 91085 in medium

Sorry if this is the wrong category, but ever since learning about Schott recently (in a way I've always known about them, like we all have) I really want one of these jackets. Anyone know where I can find one? And can anyone speak to the fit, according to the measurments, I should be a small, though I read somewhere they tend to be on the slim side. Schott still has larges. I'm 5'7, 170 lbs, anyone know the full measurements of the jacket, and if a large might work for me?
